Three bisabolene sesquiterpenes, an amine hydrochloride (8), an isocyanate (9), and an isocyano derivative (16), were isolated from a sponge, Ciocalypta sp. The structure of the isocyanate was proven by X-ray diffraction of its (p-bromobenzyl)urea derivative. From a nudibranch, Phyllidia sp., from Sri Lanka, we isolated the previously unreported 3-isocyanotheonellin (11).
